An attempt was made to relate hypnotic susceptibility to the following: an inventory of subjective nonhypnotic personal experiences, attitudes and opinions toward and interest in hypnosis, environmental and social perceptions, 5 Guilford-Martin personality scales, and measures of response styles. The Harvard Group Scale of Hypnotic Susceptibility was administered to 80 male and 97 female college students who had previously taken the questionnaires. The results and conclusions were generally negative. Judging from the present results and those in previous studies, hypnotic susceptibility is not closely related to available personality inventories or measures of "social and environmental perceptions" and probably not to measures of subjective nonhypnotic personal experiences. An S's previous hypnotic experience, attitude toward hypnosis, and expectations regarding his own hypnotizability do appear to influence his susceptibility. (40 ref.)
